Stand-up pouchesare a relatively new form of packaging and have advantages in improving product quality, enhancing shelf visual effects, portability, ease of use, freshness and seal ability.
Classification of stand-up pouch
So far, stand-up pouches are basically divided into the following five types.
1.Ordinary doypack
The general form of stand-up pouches adopts four-sealed form, which cannot be re-closed and repeatedly opened. Such stand-up pouches are generally used in industrial supplies industry.
2.Stand-up pouch with nozzle
The doypack with a suction nozzle is more convenient for pouring or sucking the contents, and can be re-closed and repeatedly opened, which can be considered as a combination of the stand-up pouch and the ordinary bottle mouth. Such stand-up pouches are generally used in daily necessities packaging, and are used to hold liquids, colloids, semi-solid products such as beverages, shower gel, shampoo, tomato paste, edible oil, jelly, etc.
3.Stand-up pouch with zipper
The stand-up pouch with a zipper can also be re-closed and repeatedly opened. Since the zipper form is not closed and the sealing strength is limited, this form is not suitable for holding liquids and volatile substances. According to the different edge sealing methods, it is divided into four-edge sealing and three-edge sealing. Four-edge sealing means that the product packaging has a layer of ordinary edge sealing besides the zipper seal at the factory. When using it, you need to tear the ordinary edge sealing. The zipper is used to achieve repeated sealing, and this method solves the disadvantage that the strength of the zipper sealing edge is not conducive to transportation. The three-edged edge is directly sealed with a zipper, which is generally used to hold light-weight products. stand-up pouches with zippers are generally used to pack some light-weight solids, such as candy, biscuits, jelly, etc., but the four-edge doypack can also be used to package heavier products such as rice and cat litter.
4.Mouth-like stand-up pouch
The mouth-like stand-up pouch combines the convenience of a stand-up pouch with a suction nozzle and the cheapness of an ordinary stand-up pouch. That is, the function of the suction nozzle is realized by the shape of the bag body. However, the stand-up pouches of the imitation mouth type cannot be reopened. Therefore, they are generally used for the packaging of single-use liquids, colloids, and semi-solid products such as beverages and jellies.
5.Special-shaped doypack
The special-shaped doypack is a new type of stand-up pouches with various shapes which are produced based on the needs of packaging and changing on the basis of the traditional bag type, such as waist design, bottom deformation design, handle design, etc. With the progress of society and the improvement of people’s aesthetic level ,and the intensification of competition in various industries, the design and printing of stand-up pouches have become more and more colorful, and there are more and more forms of expression. The development of special-shaped stand-up pouches has a tendency to gradually replace the status of traditional stand-up pouches.
